• using ‘minimal risk wagering patterns’ (that is, a set pattern of bets or stakes that unfairly minimises risks or opposite betting);

• sharing personalised promotions (that is, promotions only available to specific customers we offer them to) with others and/or taking part in any personalised promotion forwarded to you by someone else when it was not intended for you;

• colluding with other customers (that is, plotting with others to gain an unfair advantage) in relation to the promotion;

• taking advantage of broken mechanics and combination of loopholes on the game that leads to abusing the promotion/bonus; and

• purchasing all the tickets for a free game; or repeatedly depositing, cashing out and redepositing purely to gain a deposit related bonus.

b) If you take part in any play that we consider to be unfair, we may cancel any bonuses or promotions, reclaim any bonus you have received as part of any promotion we have cancelled, and either:

• void any bets funded by a bonus (that is, treat them as if they had never been placed); or

• remove any winnings relating to any bonus.

c) William Hill reserves the right to refuse the whole or part of any bet, stake or similar transaction requested by you: (a) where you have breached these terms and conditions; or (b) at any time in our sole discretion, except that we will not exercise (or seek to enforce) any such restriction if you have already made one or more qualifying bets in respect of the promotion and the exercise of our discretion would affect your ability to:

• receive the free bets, or the full expected value of the free bets, from the promotion, where you have placed all the necessary qualifying bets.

• place the remaining qualifying bets required by the promotion, and consequently receive the free bets, or the full expected value of the free bets, from the promotion, to which you would be entitled as a result; or

• without giving you notice, if the change or cancellation is needed because of any change in law or regulation; or

• by giving you notice beforehand, if the change or cancellation is for any other valid reason (for example, if there is a fault in the software or systems we use to provide this promotion, or we identify a mistake in these terms and conditions).
